Abstract: Proper cooking methods and controlled conditions can effectively retain nutrients in food. In traditional cooking methods, steaming shows more significant advantages in the retention of food nutrients. In modern heating technology, radio frequency heating greatly reduces the exposure time of food to high temperature through high-frequency electromagnetic waves, reduces the loss of heat-sensitive vitamins and effectively inhibits the maillard reaction, and steam heating effectively maintains the color, taste and vitamins of food and other nutrients. In addition, other cooking technologies and combinations such as hot air heating, radiation heating, and microwave heating have been gradually developed and applied in food processing. With the progress of science and technology, home appliances are expected to achieve more breakthroughs and innovations in the emerging cooking technology and a variety of cooking method combination technology in the future, the use of diversified cooking technology to better retain the nutritional value of ingredients, promote digestion and absorption. The personalization and integration of household appliances are used to promote the development of healthy cooking concepts and better serve people's healthy life.
